Decide on the vertex decoder JIT with CoreParameter, not the CPU core

Browse Source 
The vertex decoder JIT was enabled only when g_Config.iCpuCore was one of the
JIT cores, which tied an unrelated GPU path to the CPU setting. Headless leaned
on that by forcing iCpuCore to the interpreter after ApplyToConfig(), to keep
the decoder JIT off in the tests.

Add CoreParameter::bUseVertexDecoderJit instead. Standalone and libretro set it
wherever the host can JIT, so IR interpreter users on such hosts now get the
decoder JIT too. Headless sets it false, which keeps the test results as they
were and lets --cpu go through ApplyToConfig() like every other option.
